I have only just begun upping my levels of crystal and corn/cane sugar in my beers, but with that being said, I think it looks like it should work.
I would maybe play with beercalculus a little just to see if you may need more extract with that level of corn sugar. I just did an IPA with 9 # of LME and used 1/2# of sugar and it seems nice to me. Or another idea would be to sub some of your Crystal steeping grains for some Munich Malt Extract.
Also, I have had a revelation with clean bittering hops like Magnum or Horizon for bitterness. I used to use some High or Medium Alpha Hops for IPA's and would get green flavors (like grass) that tend to fade with a little bottle aging, but stick around when the beer is fresh. Some have said that Simcoe can give off aromas/flavors if used at the 60 Min mark (others have said the opposite). I have never used it, so try it and see.
